Sterile corneal ulceration is a serious complication in patients with keratoconjunctivitis sicca. The records of 134 patients, 19 males and 115 females, who presented with dry eyes in the Ophthalmologic Clinic were reviewed. Over a period of 6 years, 33 eyes of 23 (17%) patients developed a sterile corneal ulcer. The etiologies of dry eyes in these patients were: Primary Sjogren's syndrome: 10 cases, rheumatoid arthritis: 5 cases, ocular pemphigoid 6 cases, atopy: 1 case, local irradiation: 1 case. Patient's age and sex were not significantly associated with ulcer development (p greater than 0.05). The presence of a major underlying disease was the major contributing factor. Appropriate local treatment and patient compliance were also contributing factors. Blepharitis was found in 90% of patients.

Primary Sjogren's syndrome is an autoimmune disorder characterized by lymphocytic infiltration of the salivary and lacrimal glands, producing associated dry eyes (keratoconjunctivitis sicca), dry mouth, and intermittently swollen salivary glands. A high proportion of the infiltrating B lymphocytes express surface and cytoplasmic Ig bearing a kappa-L chain-associated CRI defined by reactivity with the murine mAb, 17.109. To determine the structural basis for CRI expression in this disease, we generated CRI+ lymphoblastoid cell lines and a cDNA library from lymphocytes extracted from Sjogren's syndrome patients' salivary gland biopsy specimens. Nucleic acid sequence analyses of the mRNA of one such 17.109-CRI+ lymphoblastoid cell line (NOV) reveals the expressed kappa light chain variable region gene (V kappa gene) to be homologous to Humkv325, a conserved V kappa gene used at relatively high frequency in certain B cell malignancies. In addition, synthetic oligonucleotides, corresponding to the first and third frameworks and the second complementarity determining region of the Humkv325 gene, were used to identify and isolate clones from a cDNA library generated from SS salivary gland lymphocytes. Clones annealing specifically with one or more of these oligonucleotide probes contained kappa light chain cDNA. The sequences corresponding to the variable region of two clones (Taykv320 and Taykv306) were homologous to Humkv325. The V kappa genes of four other cDNA clones (Taykv322, Taykv310, Taykv308, and Taykv312) most likely were generated somatically from the rearranged Humkv325 gene through a limited number of nucleic acid base substitutions. Our results suggest that the high frequency of 17.109-CRI expression in Sjogren's syndrome patients results from a multiclonal expansion of B cells using Humkv325, and that the expressed Humkv325 may undergo somatic diversification in an apparent Ag-driven response.

Primary Sjogren's syndrome (pSS) is a common autoimmune connective tissue disease in China yet without a universally accepted diagnostic criteria. In this study a new criteria was proposed and compared with other six sets of criteria. Fifty-five items in 112 pSS and 185 controls were evaluated. Results show the criteria we proposed contained one major and nine minor items. For the purpose of identifying patients in clinical studies, a major with at least three of the nine minor items or at least five of the minor items should be presented. The major item is anti-SSA/SSB(+) and the minors are, (1) dry eyes or dry mouth (> 3 months, persistently), (2) swollen salivary glands (recurrently or persistently), (3) rampant dental caries, (4) Schirmer test (< 5 mm in 5 min.) or corneal staining(+), (5) unstimulated salivary flow (< 0.03 ml/min) or abornal parotid sialography, (6) minor salivary gland biopsy (> or = 1 focus), (7) renal tubular acidosis, (8) hypergammaglobuminemia (gamma globulin > or = 30%) or hypergammaglobuminemic purpura, (9) RF > 1 : 20 or ANA > 1 : 20. Other connective tissure diseases, pre-existing lymphoma, AIDS, sarcoidosis, graft vs host disease must be excluded. The criteria we proposed had a high specificity of 98.2% and sensitivity of 94.1%.

Primary Sjogren's syndrome (pSS) is a chronic autoimmune disorder of the exocrine glands. The diagnosis is largely based on keratoconjunctivitis sicca and xerostomia in the presence of anti-SS-A and/or SS-B antibodies. Anticentromere antibodies (ACA) have occasionally been reported in patients with pSS. We describe two patients with pSS associated with ACA, initially diagnosed as limited systemic sclerosis. Symptoms at the time of initial presentation were dry eyes and mouth, arthralgias, and Raynaud's phenomenon. Both patients developed small vessel cutaneous vasculitis, parotid enlargement, low C4 complement levels, positive rheumatoid factor, and lymphoma. These findings suggest that patients with pSS who have ACA may be a subgroup of patients at increased risk of extraglandular systemic manifestations and lymphoma.

Sjogren's syndrome is an autoimmune disease that commonly presents to the ophthalmologist as a dry eye disease. We report an unusual presentation of a case of Sjogren's syndrome. A 33-year-old man presented with lid swelling, pseudomembraneous conjunctivitis with central corneal epithelial defect and history of limb weakness for past 2 years. There was progressive enlargement of the epithelial defect and conjunctival-scleral necrosis developed during follow-up. Evaluation for underlying connective tissue disorder was positive for SS-B/La antibody and, the rheumatoid factor, anti nuclear antibody, anti neutrophil cytoplasmic antibody titres were negative. Patient was diagnosed as a case of Primary Sjogren's syndrome. Resolution of the conjunctival-scleral necrosis occurred following treatment with combination of cyclosporine and prednisolone. Paramedian tarsorrhaphy was performed to promote healing of the corneal epithelium. The corneal epithelium healed, conjunctival-scleral necrosis resolved completely and the visual acuity improved to 6/36 in the right eye after 3 months of immunosuppressive therapy. The immunosuppressive therapy was discontinued after completion of 6 months of treatment. After 6 months follow-up of stopping immunosuppressive therapy, the ocular and systemic condition is stable.
